Hi Prateek.

As I previously said, based on the information you have provided I cannot draw any conclusion to what may cause your problem. To understand the events leading up to this issue the project must be debugged, either by you or me. The error codes you provide gives little insight to where or what has gone wrong in the code.

Please debug the project or upload it in a .zip file so that I can debug it.

Hi.

I'm not able to reproduce the error with the main.c file and sdk_config.h file you supplied. Could you please upload the project in a .zip file or do a debug in Segger Embedded Studio as I suggested previous?

Hi Prateek.

I really need more information in order to be able to help you. Can you post any debug output? Output during the dfu? Are you using Watchdog? Can you please add your main.c and sdk_config.h?

Hi Prateek.

I really recommend that you install Segger Embedded Studio and use that for your development, you can get a free licence with no limitations when you are working with Nordic products, there is an introduction and install guide on our infocenter. There is not much more I can say without debugging your code, which I dont have. So I recommend you install Segger and debug, or attach your project in this question.

Thanks.

Hi Prateek.

Have you defined DEBUG in the preprocessor? If not please define DEBUG.

And add a break point to NRF_LOG_ERROR("Received an error:0x%08x!", error_code); in the function void app_error_handler_bare(uint32_t error_code)

This is the function found in main.c in the bootloader_secure_ble project:

void app_error_handler_bare(uint32_t error_code)
{
    (void)error_code;
    NRF_LOG_ERROR("Received an error: 0x%08x!", error_code);
    NVIC_SystemReset();
}

What error code do you get?

Please post it.

Hi Prateek.

Have you debugged your code while you try to perform the DFU to see where the problem occurs?

Hi Andreas,

I am using my custom code with the help of DFU Bootloader Example.

In Previous, i am using sdk-11 which works fine in dfu and i am not getting any issue with DFU, while currently i am upgrading my sdk to 14.2 in which i am getting this issue.

Thanks,

Prateek

Hi Prateek.

Which examples are you using? Are you using any of the DFU bootloader examples, and which one?
